Impact Analysis showing latest revision

I am trying to do a "where used" impact analysis on an assembly and the results include all revisions of the higher level assemblies. Is there a way to only show the latest revisions of each higher assembly? I tried setting different "rules" or "filter by" options but they don't seem to be making any difference. Is there a particular combination of the "rule", "display" and "filter by" items that I should be selecting?
